There should be another BASS update released tomorrow or early next week. The main reason for the update is to fix a bug affecting the new BASS_NODEVICE option, which also affects using encoded soundfonts/samples with the latest BASSMIDI version (it uses the BASS_NODEVICE option internally). The fix is present in the "stuff" builds, so I would indeed recommend using it in the meantime if you may be affected by that bug. Besides that fix, the latest stuff (2.4.13.7 currently) also has a couple of tweaks for BASS_ChannelGetData, and adds a 0x10000 flag to the BASS_CHANNELINFO "origres" value to indicate floating-point files.
